I removed your additions to Bakkhali in part because they violated our Wikitravel:Don't tout policy—adding more than one listing per establishment to an article is prohibited. The other reason is that we have a big problem on this article with Kolkata booking agencies fraudulently replacing hotel/resort phone numbers with their own. Recently they have taken to adding new hotel listings with their own phone numbers included. The fact that you repeated the phone number twice struck me as suspicious. --Peter Talk 03:26, 6 April 2009 (EDT)
